What's the difference between scattered and speckle?

Scattered


Definition:

  • (imp. & p. p.) of Scatter
  • (a.) Dispersed; dissipated; sprinkled, or loosely spread.
  • (a.) Irregular in position; having no regular order; as, scattered leaves.

  • (19) From the different shapes of the scattering curves of the native phosphofructokinase at pH 7.5 in the presence of 15 mM ATP and of the cross-linked tetramer or octamer, it can be inferred that the shapes of the protomers are different: in the presence of ATP the protomers are elongated, having an axial ratio of 1.8 to 2.0; the cross-linked state reveals a spherical protomer of radius 33.0 A, similar to that of the native enzyme at pH 7.5 in the presence of fructose 6-phosphate or fructose 1,6-bisphosphate.
  • (20) Cells taking up label are found scattered throughout the large cartilaginous epiphyses.

Speckle


Definition:

  • (n.) A little or spot in or anything, of a different substance or color from that of the thing itself.
  • (v. t.) To mark with small spots of a different color from that of the rest of the surface; to variegate with spots of a different color from the ground or surface.

Example Sentences:

  • (1) The nuclear origin of the Ha antigen was confirmed by the speckled nuclear immunofluorescence staining pattern given by purified antibody to Ha obtained from a specific immune precipitate.
  • (2) Ensemble averaging of a large number of unfiltered spectra was used as the "gold standard" in the evaluation, i.e., as the output of an ideal filter which reveals the exact nature of the underlying Doppler spectrum after speckle has been eliminated.
